CHECK-WIRE REEL FOR SEEDlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 576,408, dated February 2, 1897..

Application filed November 16,1896- Serial No. 612,305. (No model.)

T0 at whom it may cancer/1 Be it known that I, AUGUST LINDGREN, of Moline, county of Rock Island and State of Illinois, have invented a new and useful Improvement in Checkire Reels for Seeding- Machines, of which the following is a specification.

This invention relates to an attachment for reeling or unreeling the check-wire of seeding-machines, the object of the invention being to provide a device of this character which may be operated automatically from the ground-wheel irrespective of the character of the rim of the wheel, whether flat, coucave, split, or otherwise.

With these ends in view my invention consists in combining with a reel adapted to receive the coils of the wire a friction device connected to the reel and comprising two disks or members yieldingly connected together and arranged to embrace the peripheral edges of the rim of the ground-wheel.

The invention also consists in the details of construction and combination of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a rear elevation of suchportions of the frame of the seeding-machine as are necessary to illustrate my invention,showing my improved reeling attachment applied thereto. Fig. 2 is a side elevation of the same with the reel proper removed. Fig. 3 is a vertical longitudinal section through the friction device, the reel and the ground-wheel of the machine on an enlarged scale, showing the manner in which the rim of the wheel is embraced between the friction-disks.

Referring to the drawings, 1 represents the rear portion of the framing of the machine sustained, as usual, by the ground-wheels, one only being shown.

2 represents a bracket or arm which is extended transversely along the framing in the rear of the ground-wheel and securely held in clips 3, fixed to the framing. This bracketarm is preferably cylindrical in cross-section, is extended. upward at the side of the framing inward of the ground-wheel, then horizontally above the axis of the wheel and beyond the same, forming an axle 4, upon which the friction device and reel are mounted to revolve in the manner now to be described. The friction device comprises two members in the form of an inner disk 5 and an outer disk 6, the latter being formed at its center with a hub or sleeve 7, fitting loosely on the axle-arm, and to the outer end of this hub the reel 8 is securely attached. The inner disk 5 is formed at its center to fit snugly around the axle, and is provided with an outwardly-extending sleeve or hub 9, which encircles the axle and fits snugly but easily over the innerend of the hub 7 in such manner that the two disks may be moved to and from each-other. The disks are held together by means of a series of bolts 10, which are extended from the outer disk through the inner disk and beyond the same, where these bolts are encircled by spiral springs 11, which latter are confined by nuts 12, the springs bearing at their ends respectively against the disks and nuts and tending to force the disks with a yielding pressure toward each other. The adjacent faces of the disks near their peripheral edges are formed with bearing-surfaces 13, extending in the plane of the disks, and these bearing-surfaces, when the disk is in operation, embrace between them the edges of the rim of the ground-wheel, the springs holding the disks firmly against the edges of the wheel and insuring their rotation as the wheel is revolved.

It will be observed that by reason of the construction described the friction-disk may be applied to wheels irrespective of the particular form of their rims and irrespective of the width of the rim of the wheel, the telescoping feature of the disks and their connection by means of the bolts and springs adapting them to be adjusted to the rim of the wheel and insuring their frictional contact therewith.

I may employ in connection with my improved friction device a reel of any suitable character which will receive the coils of the check-wire, but I prefer to adopt the construction illustrated, which is simple and possesses strength and durability. This reel consists of a series of radial arms 14,securely connected at their inner ends to a spider or hub 15,which latter is formed with an opening to receive the outer end of the hub 7 and to which it is firmly attached by means of pins 16. The

outer ends of these arms are split, and the split ends bent in opposite directions outward, forming forks within which the coils of the wire are received.

As shown in Fig. 2, the bracket-arm which sustains the friction device and reel extends at a forward inclination, the weight of these parts insuring the engagement of the friction device with the ground-wheel. A brace-rod 17 is attached to the axle 4L and extends downward and forward to the framing,where it is secured and serves to prevent the friction device from accidentally leaving the groundwheel.

Having thus described my invention, what I claim is- 1. A reeling attachment for seeding-machines comprising a friction device consisting of two members adapted to yieldingly embrace the edges of the ground-wheel and receive motion therefrom, and a reel adapted to receive the coils of the check-wire and operatively connected to the friction device.

2. A reeling attachment for seeding-machines comprising an axle or support adapted to be connected to the machine, a friction device comprising two members mounted to revolve on said axle and connected together to yieldingly embrace the edge of the groundwheel and a reel operativelyconnected to said friction device.

3. A reeling attachment for seeding-machines comprising an axle adapted to be connected to the framing of a machine, a friction device consisting of two disks provided with hubs encircling said axle and telescoping at their adjacent ends, devices yieldingly connecting said disks and a reel operatively connected to said friction device.

4. In a reeling attachment the combination with the supporting-axle adapted to be connected to the machine, of two friction-disks mounted loosely on the axle-bolts connecting said disks, springs encircling the bolts and tending to force the disks toward each other and a reel connected to one of said disks.

5. In a reeling attachment the combination with the axle, of the two disks mounted to revolve thereon, bolts connecting said disks, nuts on the ends of the bolts, spiral springs encircling said bolts between the adjacent disk and the nuts, and a reel connected to one of said disks.

6. The combination with the supportingaxle adapted to be connected to the machine, of an inner friction-disk loosely encircling the axle and provided with an outwardly-extending sleeve or hub, an outer friction-disk also encircling the axle and provided with a hub, the inner end of which extends in the adjacent end of the hub on the first-named disk, a series of bolts extending from one of the disks through the other and beyond the same, nuts on said bolts, spiral springs encircling the bolts between the disk and the nuts and a reel fixed to the outer end of the hub of the outer disk.

In testimony whereof I hereunto set my hand, this 24th day of October, 1896, in the presence of two attesting witnesses.

AUGUST LINDGREN.
